The stainless steel free‑float steam trap drives the opening and closing of the float through condensate level change inside the valve body. It automatically drains condensate and prevents steam escape. When the steam system starts‑up, air inside the pipeline is discharged via automatic or manual air vent. When condensate flows into the valve, the float rises under buoyancy to open the valve, so air and condensate are quickly discharged together. As hot condensate and steam enter, internal temperature rises and the air vent closes. The float automatically lifts and drops according to condensate volume and water‑level variation to adjust the opening of seat orifice and realize continuous condensate drainage. When condensate inflow stops, the float sinks by its own weight to block the seat orifice and close the valve. Since the seat orifice is always below the condensate liquid level, reliable water‑seal is formed without steam leakage, realizing the function of draining water and blocking steam.

Product Advantages of Stainless Steel Free‑Float Steam Trap

The stainless steel free‑float steam trap features simple structure. Inside there is only one movable component‑‑precision‑ground stainless steel hollow float, which serves as both floater and closing member. Without vulnerable parts, it delivers long service life. It is immune to temperature and working‑pressure fluctuation and enables continuous drainage. Two air‑vent arrangements are available: air vent mounted on the upper part of valve cover, or air vent installed inside valve body.
